NUT-LOCK.

SPECIFICATION forming part of Letters Patent N 0. 377.714, datedFebruary 7, 1888.

Application filed February 12, 1887. Serial No. 227,453. (No model.)

To all whom it may concern:

. Be it known that I, WILLIAM H. HAWS, of (Little) Washington, in thecounty of Washington and State of Pennsylvania, have invented certainnew and useful Improvements in N ut-Locks; and I do hereby declare thatthe following isa full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had'to the accompanying drawings,and to the letters of reference marked thereon, which form part of thisspecification.

My improvement relates to that class of de- I 5 vices known asnut-locks, and has for its object a novel, simple, and effective meanswhereby the nuts, when. screwed upon the b0lts,are securely and firmlyheld from becoming loose or turning, and, further, in forming the lockout of one piece of metal and so bending the same that the portion whichfits under the inner not will always be held tightly against it; and itvalso consists in certain other details of construction, as will behereinafter 2 more fully decsribed, and specifically pointed out in theclaim. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which- Figure l is a perspective view of mynut- 0 lock, showing thesame when applied. Fig. 2 is a perspective viewof the lock-plate, and Fig. 3 is a modification of the lock-plate.

In the drawings, A represents an ordinary rail to which are secured thefish-plates B B. 5 The railand fish-plates are provided with holes orperforations, through which ordinary screw bolts,O,are adapted to pass.A nut, D, is then screwed upon the bolt until the fish-plates arebrought firmly and tightly against the web of 40 the rail.

v F represents my improved nut-lock, which is preferably formed ofmalleable metal, and in contour rectangular in. shape, as shown in Fig.2. At a suitable distance from its top I 5 cut or stamp out an aperture,f,wh ich may be of any shape desired,for the purpose of allowing thebolt to pass through. Below the aperture); I bend the plate at anincline, as shown at f, and almost at right angles with the main D isthe outside nut,between which nut and I the nut D is the locking-plateF.

The operation is as follows: The bolt being passed through the railandfish-plates, the nut D is screwed up tightly. The locking-plateis thenput in place by putting it on the bolt. Then the outside nut is screwedup ti htly and firmly against thelocking-plate, Willi is then bent overand down upon the top of the nut. It will be readily seen that by thesemeans a simple, cheap, and effective nut-lock is produced which can bemanufactured at but little cost, and can,when required, be readilyremoved to allow repairs when necessary.

In Fig. 3 I also show a modification in which the lower portion of thelocking-plate is bent, as shown, to form the bearing portions gand g andthe part 9, which is adapted to fit snugly against the lower side of theinner nut,

the upper portion of the plate being bentover the outer nut, as beforedescribed.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, is

As a new article of manufacture, a lockingblank for nuts, consisting ofa piece of metal having a perforation to admit a bolt, one end bent andthe other end provided with a springflange, whereby it may be wedgedbetween a washer and one of the parts bolted together, the other endbeing long enough to be bent over the nut, so as to lock the same,substantially as described.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses.
